I have the Droid X and although it is a nice piece of equipment, I find it slow to respond. I feel I can think and act faster than the device can respond. The phone quality I find is much better with the iPhone 4 than the Droid when receiving or making calls. Apps, that is another story as I find my co-workers that have iPhones have nicer apps than available for the Droid. Another issue is music. I like the idea of using my iTunes with a device other than a Nano. I could upload the songs into my iTunes on my laptop then sync it to the iPhone and have the best of both worlds without having to carry two devices.
I have been with Verizon for years and Verizon will release the iPhone5 next month. I am already on the list to get one and most likely try to sell this
Droid X on ebay or something.
Anyhow, this is just my $.02 ....
